endlessly. Only reboot helps. I can't connect to the access point "Rtl Fallback Hotspot" either.

Everything is fine on bekken chips. only realtek problem

[ferbulous]

What about after ota update? Can it still reconnect to wifi or do you still need to power cycle

@kuba2k2 wrong tag, should be Realtek, not BK7231.

Hi, I'm having a similar issue. With the SSID hidden, I cannot connect (even with fast_connect=True). When publishing the SSID it works without issues.

Chip is a Realtek AmebaZ from the Solis Wifi Stick of this wonderful project.

Is there anything I can do to facilitate troubleshooting?

Thank you in advance, Erwin

Hi, same issue here as ErwinP has. There is no connection with a hidden SSID. Either with or without fast_connect=True. Module board: t102-v1.1 with RTL8710BX Log error: bssid=00:00:00:00:00:00 reason='Unspecified' It works normally with exposed SSID.
